FAYETTEVILLE – Other than the disturbing surprise of a possible overnight arson performed on fourth-year starting quarterback Brandon Allen's vehicle, there were some surprises of the more conventional sort Monday associated with Arkansas Razorbacks releasing their season-opening depth chart.

Arkansas head coach Bret Bielema unveiled a 2-deep, and in some cases 3-deep, with the Razorbacks opening the season at 3 p.m. Saturday on SEC Network TV in Auburn, Ala., against the reigning SEC champion Auburn Tigers.

Allen, whose car was reported on fire at 4 a.m. Monday while parked by his Fayetteville residence, and his brother, redshirt freshman Austin Allen, are the No. 1 and No. 2 quarterbacks as they have been throughout the August preseason.

They quarterback an offense whose depth chart reflects no significant first-team changes from the August preseason outset, but some second-team shuffling along the line.

Cameron Jefferson — the senior transfer from UNLV originally expected to contend at offensive guard — now is listed the second-team left tackle behind sophomore incumbent Dan Skipper.

Also rather than a fullback, the depth chart lists two tight ends positions with returning sophomore All-SEC second-teamer Hunter Henry at one — backed by junior Alex Voelzke — while the other tight end lists senior AJ Derby and sophomore Jeremy Sprinkle.

At running back, Arkansas has a three-headed operation with junior Jonathan Williams and sophomore Alex Collins (last year's SEC Freshman of the Year) — both on the Doak Walker Award watch list — and sophomore Korliss Marshall as Bielema lists all three as first team.

"I have listed two tight ends because we are a team that would like to feature multiple tight end sets, as well as using multiple running backs," Bielema said of tight ends playing H-back or fullback. "I listed all three of our running backs as tie because each guy has a set plan I want to be able to execute with him."

At the wide receivers, Bielema lists three flankers, with junior Keon Hatcher and sophomore Drew Morgan as co-first-teamers, and true freshman Jared Cornelius alternating as a second-teamer.

Skipper and Jefferson rank 1-2 at left tackle, with senior incumbent Brey Cook at right tackle backed by true freshman Brian Wallace.

True freshman Frank Ragnow is the backup center, with JC transfer Sebastian Tretola backing Charpentier at left guard and junior Austin Beck is listed at right guard behind Kirkland.

Tretola has "really opened our eyes," pushing Charpentier, Bielema said. While he won't start, "Ragnow will play," the head coach said.

Defense does have some injury related surprises.

Deatrich Wise, a first-team defensive end at the August outset — but recently idled by a sprained knee — is just now practicing again and listed a co first-teamer with his recent replacement, fellow third-year sophomore JaMichael Winston.

Off of last Friday's dress rehearsal mock game, Bielema said, "The coaches felt really good with where we are at as a football team. I felt the mock game went exceptionally well. Better than a year ago."
